Two flame-sealed ampules each containing 30 g of soil are ready-to-use. Use with EPA Method 8270, or other applicable method. Includes a subset of the analytes listed below at 1000–15,000 ?g/kg.

NOTE: The assigned value for 4-Methylphenol represents 3-Methylphenol plus 4-Methylphenol combined; as the isomers cannot be distinguished chromatographically or spectrally. Therefore, Waters ERA groups the two isomers together and reports them both as 4-Methylphenol. The Performance Report will only list 4-Methylphenol.
